Do you have SM 4.0? I do, and the installation of IOS222 failed as well
The Waninkoko installer works like a charm, but kwiirk's installer unfortunately doesn't...
Does anyone have a solution for this?

You downgraded but it doesn't work?
That's strange. Considering that Waninkoko's cIOS installed flawlessly on 4.0, it's probably a bug in the installer. Either that, or the installer uses an official IOS instead of cIOS 249, even if 249 is present.
